Estimation & Control for Battery Management & Ocean Observing
Energy and environment are fundamental challenges facing the human society nowadays. High hopes have been given to a bright future enabled by advanced energy management and environmental monitoring technologies. Recent studies have demonstrated the promise of control theory as a theoretical basis and thinking tool for tackling challenges in the two areas.
In this talk, I will present my research on battery management and ocean observation. The two seemingly distinct problems are inherently related: their solutions share a common foundation in optimal estimation theory. Battery-based energy storage is a major building block of renewable energy facilities and electric vehicles. Maximizing batteries’ operational safety, performance and lifetime largely depends on real-time state-of-charge estimation. For this problem, I will present solution strategies based on adaptive and multi-model estimation. Not only will they reduce the complexity of battery management, but also improve estimation accuracy in the presence of complicated battery dynamics. I will then describe my work on ocean flow field reconstruction via analysis of observation data collected from drifters. The considered problem boils down to nonlinear simultaneous input and state estimation, which will be explored and addressed. This work can help oceanographers understand flows and their impact on transportation of nutrients, motion of biological species, and diffusion of contaminants. In addition, it possesses significant implications for the design of renewable (wind, solar, etc.) energy observation and prediction systems. Such systems play an important role in efficient renewable energy harvesting.

Recently my research group in the Microfluidics Laboratory at Purdue University has harnessed the power of light and electric fields to develop several novel ways for non-contact manipulation of droplets and particles with potential applications in the bio/medical/chemical/pharma industries. These are generally described as opto/electric droplet manipulation and opto/electric particle manipulation. I will present the fundamental principles behind these methods, what their capabilities are, and what their potential uses are.
Opto/electric droplet manipulation: using lasers and electric fields we can control and manipulate individual droplets to perform assays and other chemical operations. This method is similar to opto-electrowetting (OEW or EWOD) except that the “electrodes” used for the droplet manipulation are virtual electrodes whose locations are defined by dynamic laser light patterns rather than fixed, unmovable conventional electrodes.
Opto/electric particle manipulation: using lasers and electric fields we can capture, concentrate, manipulate and sort populations of micro- and nanometer-scaled “particles”. These “particles” range in size from single molecules (DNA, proteins, etc.) to nanoparticles (quantum dots, carbon nanotubes, nano-scaled polystyrene latex beads, etc.) to complex biological organisms (bacteria, mammalian cells, etc.). This novel technique called Rapid Electrokinetic Patterning (REP) combines features of optical trapping (OT) and dielectrophoresis (DEP) in an innovative, dynamic way using a simple parallel plate electrode configuration. Transparent Indium Tin Oxide (ITO) electrodes on glass substrates apply an electric field to the fluid carrying the particles but also to allow light into and out of the fluid. Near-IR laser illumination causes subtle localized heating, creating an electric permittivity gradient that in turn drives a global microscopic toroidal vortex. The vortex efficiently transports particles to a preferred location, usually the surface of the electrode where they are non-permanently collected. They can then be released or permanently fixed in place by the application of a low frequency electric field.
Professor Wereley completed his masters and doctoral research at Northwestern University. He joined the Purdue University faculty in August of 1999 after a two-year postdoctoral appointment at the University of California Santa Barbara. During his time at UCSB he worked with a group developing, patenting, and licensing to TSI, Inc., the micro-Particle Image Velocimetry technique. His current research interests include opto/electrokinetics, investigating microscopic biological flows, harnessing diffusion for sensing applications, and developing new ways of measuring flows at the smallest length scales. Professor Wereley is the co-author of Fundamentals and Applications of Microfluidics (Artech House, 2002 and 2006) and Particle Image Velocimetry: A Practical Guide (Springer, 2007). He is on the editorial board of Experiments in Fluids and is an Associate Editor of Springer’s Microfluidics and Nanofluidics. Professor Wereley has edited Springer’s recent Encyclopedia of Microfluidics and Nanofluidics and Kluwer’s BioMEMS and Biomedical Nanotechnology.

Neuronal Correlates of Social Behavior in Mushroom Body Extrinsic Neurons
Speaker: Benjamin H Paffhausen
Institute of Biology, Neurobiology, Freie Universität Berlin, Germany
So far no data exist about the neural correlates of social interaction in the honeybee. Werecord from multiple mushroom body extrinsic neurons during social interaction in a smallfunctioning honeybee colony. The bees cared for the queen, nursed the brood, guarded theexit, cleaned the hive and foraged. The colony used the honeycombs as they wouldnaturally. The recorded bee behaved normal. The weight of the highly flexible twisted tripleof wires was counterbalanced by a loose nylon spring. The behavior of both the recordedanimal and the hive mates was monitored in infrared by a video camera and later tracked.Up to 4 neurons were recorded simultaneously and lasted for up to 47 hours per animal.Spontaneous spike rates were lower than those of similar neurons in harnessed bees. Socialinteractions, location on the comb and body directions were not encoded by specific neuralactivities of selected units but rather by the combination of several units.Neural activity increases frequently during interactions. Furthermore, we find that thevariance of spike activity of the units increases suggesting that the neurons sense orcontrols the contacts with other bees. Hints were found that different activity patterns acrossneurons changes with different forms of social interactions. Ongoing analysis, that includemachine learning, are pursued to clarify whether the activity changes are related to, forexample, the origin of the approaching bee or the division of labor within the bee colony. Thehighly variability of neural activity needs further analyses.
An Experimental Study on the Aerodynamic Performance of Flexible Tandem Wings
Speaker: Zheng Yingying
As typical four-wing insects, the dragonflies have the features of both flexible wing and tandem-wing configuration. In previous studies, these two features have been widely studied and proven to account much for the great flight capability of the dragonflies. However, these two features were usually concerned separately. How the flexibility will affect the performance of tandem wings, and how tandem-wing configuration will affect the performance of flexible wings are still unknown. Therefore, the present work aims to study the combined effects of the wing flexibility and tandem configuration by investigating the aerodynamic performance of flexible tandem wings.
Three sets of dragonfly-like flexible tandem wings termed Wing I, Wing II and Wing III, and a set of rigid tandem wings as references were investigated in a hovering and two forward flights (St = 0.3 and 0.6). Three phase differences between the forewing and hindwing, i.e. , 9and , were employed. The results of force measurements showed that both the flexibility and phase difference had significant effects on the aerodynamic performance of flexible tandem wings. Generally, the tandem Wing III models with appropriate flexibility outperformed the other tandem wing models. The most favorable phase difference for different wing models varied. According to deformation measurements, the bending deformation of flexible wings was found to cause lags of wings’ locations in plunging direction as compared to the rigid wings. Both phase-locked PIV and time-resolved PIV measurements were carried out. Comparing the flow fields of Wing III models and rigid tandem wings, the lags contributed to the force generation of Wing III models by making the LEVs closer to the wings. Besides, the lags restrained the shedding of LEVs on the Wing III models as compared to that on the rigid wings, which also offered benefits to the Wing III models. What is more important, the lags modified the separation between forewing and hindwing, which resulted in different forewing-hindwing interactions between the tandem Wing III models and tandem rigid wings.
